Operators

An Operator is a symbol which operates on a value or date representing a specific action on working with data. It tells compiler to perform specific mathematical or logical functions.

The value or data on which the operators operates is called operand.

Arithmetic Operators​

Addition Operator​

The Addition Operator "+" is used to add numbers or strings

set x = 1;
set y = 2;
set z = x + y; // Performs arithmetic addition

put(z);   // Prints 3

Subtraction Operator​

The Subtraction Operator "-" is used to add numbers or strings

set x = 4;
set y = 2;
set z = x - y; // Performs arithmetic subtraction

put(z);   // Prints 2

Multiplication Operator​

The Multiplication Operator "*" is used to add numbers or strings

set x = 4;
set y = 5;
set z = x * y; // Performs arithmetic multiplication

put(z);   // Prints 20

Division Operator​

The Division Operator "/" is used to add numbers or strings

set x = 10;
set y = 4;
set z = x / y; // Performs arithmetic division

put(z);   // Prints 2.5

Logical Operators​

Equality Operator​

The "==" operator returns true if the two operands are equal, else returns false

set x = 10;
set y = 4;
set z = x == y; // Performs equality comparison

put(z);   // Prints false

Less/Greater Than Operator​

The "<" and ">" operators respectively check if first operand is less than or greater than the second operator

set x = 10;
set y = 4;

set z = x < y; // Performs less than comparison and assigns the value to z

put(z);   // Prints false

set z = x > y;  // Performs greater than comparison and assigns the value to z

put(z);   // Prints true

LessEqual/GreaterEqual Operator​

The "<=" and ">=" operators respectively check if first operand is less than equal to or greater than equal to the second operator

set x = 10;
set y = 4;

set z = x<=y; // Performs less than equal to comparison and assigns the value to z

put(z);   // Prints false

anew x = 4;

set z = x>=y;  // Performs greater than equal to comparison and assigns the value to z

put(z);   // Prints true

Tide/In Operator​

The "~" operator returns true if a certain key is present in an object else, returns false

set maintainers = {
  "Alen": {
    "age": 18
  },
  "Prajjwal": {
    "age": 21
  },
  "Shubham": {
    "age": 20
  },
  "Ganesh": {
    "age": 21
  }
};

set is_maintainer = fun (name) {
  return name ~ maintainers;
};

put(is_maintainer("Shubham")); // Prints true
put(is_maintainer("Bilal")); // Prints false

Bitwise Operators​

Left Shift Operator​

The "<<" operator shifts the bits of the left operand to the left by the number of bits specified in the right operand.

set x = 10;
set y = 2;
set z = x << y; // Performs left shift
put(z);   // Prints 40

### Left Shift Operator

The ">>" operator shifts the bits of the left operand to the right by the number of bits specified in the right operand.

```etrl
set x = 20
set y = 2
set z = x >> y; // Performs right shift
put(z);   // Prints 5

Bitwise AND Operator​

"&" operator performs bitwise AND operation on two operands.

set x = 120;
set y = 15;
set z = x & y; // Performs bitwise AND
put(z);   // Prints 8

Bitwise OR Operator​

"|" operator performs bitwise OR operation on two operands.

set x = 240;
set y = 15;
set z = x | y; // Performs bitwise OR
put(z);   // Prints 255

Bitwise XOR Operator​

The "^" operator performs bitwise XOR operation on two operands.

set x = 360;
set y = 20;
set z = x ^ y; // Performs bitwise XOR
put(z);   // Prints 380
